CVE-2022-2962 1 Qemu 1 Qemu 2025-04-23 7.8 High
A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame, it doesn't check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers multiple times, possibly leading to a stack or heap overflow. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.
CVE-2017-7493 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 7.8 High
Quick Emulator (Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to an improper access control issue. It could occur while accessing virtfs metadata files in mapped-file security mode. A guest user could use this flaw to escalate their privileges inside guest.
CVE-2017-7377 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 6.0 Medium
The (1) v9fs_create and (2) v9fs_lcreate functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS privileged users to cause a denial of service (file descriptor or memory consumption) via vectors related to an already in-use fid.
CVE-2017-12809 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 6.5 Medium

CVE-2017-5526 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 6.5 Medium
Memory leak in hw/audio/es1370.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption and QEMU process crash) via a large number of device unplug operations.
CVE-2015-7549 1 Qemu 1 Qemu 2025-04-20 N/A
The MSI-X MMIO support in hw/pci/msix.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (NULL pointer dereference and QEMU process crash) by leveraging failure to define the .write method.
CVE-2017-9060 1 Qemu 1 Qemu 2025-04-20 5.5 Medium
Memory leak in the virtio_gpu_set_scanout function in hw/display/virtio-gpu.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (memory consumption) via a large number of "VIRTIO_GPU_CMD_SET_SCANOUT:" commands.
CVE-2017-8380 1 Qemu 1 Qemu 2025-04-20 N/A
Buffer overflow in the "megasas_mmio_write" function in Qemu 2.9.0 allows remote attackers to have unspecified impact via unknown vectors.
CVE-2017-9503 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 5.5 Medium
QEMU (aka Quick Emulator), when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, allows local guest OS privileged users to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors involving megasas command processing.
CVE-2017-8112 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 6.5 Medium
hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (infinite loop and CPU consumption) via the message ring page count.

CVE-2017-8284 1 Qemu 1 Qemu 2025-04-20 N/A
The disas_insn function in target/i386/translate.c in QEMU before 2.9.0, when TCG mode without hardware acceleration is used, does not limit the instruction size, which allows local users to gain privileges by creating a modified basic block that injects code into a setuid program, as demonstrated by procmail. NOTE: the vendor has stated "this bug does not violate any security guarantees QEMU makes.
